Yes! Thank you, that is indeed the model  :cheesy:

All transistors.

Looking at the circuit board/scheme what would perhaps be the best place to start?

If necessary I shall disassemble it once again, unscrew the board, flip it and take a picture.

Many thanks gentlemen, please keep the advice coming, much appreciated. :tu:

The Newcomer's Forum / Univox 65 - Hissy Reverb?
« on: October 19, 2015, 07:01:21 AM »
Well firstly - Hello All  :) My frist post, and I hope not my last.

I have a couple of Japanese SS amps - ELK 103 Viking (Head), ELK 75 Bass Head and Cab and as from yesterday a Univox 65. And I love em!

The last one is my query of today which perhaps experienced minds can help me with  ???

It has a slightly higher than normal (what I consider to be normal) background hum when in use, but in particular the Reverb is rendered almost unusable when turned on, even a 1/4 of the the dial leads to a pretty loud hiss/white noise.

I just took the whole shebang apart. Pretty clean and tidy inside, no loose cables or dodgy connections when poking as far as I can see. The reverb unit (which I believe to be spring reverb) is housed in a rubber/foam sealed housing for isolation.

So where should I perhaps start. Cap replacement? Or some amateur shielding?

Here's a YouTube video highlighting the problem:

Many thanks!
